Loading the Recently Selected Value in the Combobox

Question

Hi Experts,

I need your assistance, I need to load the last recently Selected value in the combobox
every time when I load the Form.

1. I have added the Items to the Combobox.

<-Select->
ABAP
SAP
Oracle
SQL Server

2. Initially when I load the Form, the combo box will be empty and I will give select "SQL Server".
3. Once after exiting the form, when I load again the combobox is empty.

But, It should have the Selected Text "SQL Server" as that was the last recently selected form the combo box.

Help me to solve this. Anyhelp appreciated.

Thanks in Advance.
